Subaru H6 Standalone ECU Plug and Play Harness

This is our standalone ECU Plug and Play harness for Subaru H6 swaps. After releasing our ECU Bundles, we received a lot of requests for quotes for just the harness, so here it is! This harness can be made for any standalone ECU, including Link, Haltech, EMtron, MoTeC, and more. These kits will include the following:

• A terminated harness for the ECU of your choosing (email us before ordering to confirm your ECU will work)
• ReetWire ECU Header Breakout Kit (coming soon for individual sale!)
• DBW Accelerator Pedal Harness (when applicable)
  
• Stickers!

The harness utilizes a Mil-Spec bulkhead connector for passing through the firewall. You will need to send us a measurement from the engine harness connectors, to where you want the Mil-Spec connector to go through the firewall; and you will need to send us a measurement from where you want the Mil-Spec connector on the firewall, to where you want to mount the ECU inside the vehicle. It is assumed you will provide all necessary electronics (standalone ECU, wideband O2 control, IAT sensor, etc.) If you want something you don't see available, feel free to visit our Contact page.

All factory vehicle functions are retained with this harness. A/C, headlights, power windows, radio, cruise control, etc. will all still function. For non-CANBUS vehicles, these sytems function on their own, and do not rely on the ECU. For CANBUS vehicles, these systems still function on their own, but look to the ECU for proper CAN communication. Many standalones, including Link and Haltech ECUs, have the ability to communicate with the factory CANBUS systems, ensuring everything in your vehicle functions properly, even without the factory ECU.

Current Build Time: 3-4 months
